Abstract: A user profile generating system for generating a user profile for use with a processing device operable to display content includes: a head motion tracking unit operable to identify head motion of the user, an eye motion tracking unit operable to identify eye motion of the user, and a profile generating unit operable to generate a user profile comprising head tracking and eye tracking information for the user, where the generated user profile is used to modify interactions between the user and a processing device.

Abstract: A head-mounted display (HMD) apparatus comprises a head attachment unit comprising a first attachment member configured to attach the HMD to a user's head when the HMD is worn by the user and a first element having an adjustable weight distribution, and an adjustment unit configured to adjust a distribution of the weight of the HMD based on user profile information associated with the user, wherein the adjustment unit is configured to adjust the weight distribution of the first element of the HMD based on the user profile information by adjusting a configuration of one or more mobile components of the first element without adjusting a position or an orientation of the first element with respect to the HMD.

Abstract: An image rendering system for generating one or more images of a virtual environment, the system comprising an object identifying unit operable to identify one or more objects in the virtual environment, and to identify one or more rendering parameters associated with each object, and a rendering unit operable to render an image comprising one or more of the identified objects in accordance with the corresponding rendering parameter, wherein the rendering parameter specifies a respective minimum level of detail with which the object is to be rendered.

Abstract: An image rendering instruction generation system includes an object identification unit operable to identify one or more objects for rendering in a virtual scene, a shader identification unit operable to identify a shader for rendering the identified objects, wherein the shader comprises two or more shading processes corresponding to different levels of detail, a draw call generation unit operable to generate a draw call comprising the identified shader, and a draw call output unit operable to provide the generated draw call to an image rendering system.

Abstract: A processing system for modifying interactive content in dependence upon a user profile includes: a user profile obtaining unit operable to obtain the user profile comprising information about head motion and eye motion for a user, an interactive element identification unit operable to identify interactive elements in displayed content, and a content modification unit operable to modify interactions between a user and one or more of the identified interactive elements in dependence upon the obtained user profile.

Abstract: A user input system for controlling a viewpoint within displayed content includes a user profile obtaining unit operable to obtain a user profile having information about head motion and eye motion for a user, an input unit operable to receive user inputs relating to a change in viewpoint within displayed content, the user inputs including the user's head motion, and a viewpoint modification unit operable to modify the viewpoint in the displayed content in dependence upon received inputs and the user profile, where the modification to the viewpoint includes a greater motion than the head motion received as an input.

Abstract: A foveated rendering system for modifying content to be displayed includes a user profile obtaining unit operable to obtain a user profile comprising information about head motion and eye motion for a user, and a foveated rendering unit operable to apply a foveated rendering process to the content to be displayed in dependence upon obtained user profile information.

Abstract: A method of generating video frames for a cloud-based video game includes obtaining, via a communications network, a plurality of frames of a video game rendered at a cloud device; obtaining a player input received at an input device, the input device being used to play the video game, the player input being received in response to the display of at least one of the obtained video frames; inputting at least one of the obtained video frames and the player input to a prediction model; and synthesizing, based on the output of the prediction model, a subsequent frame for output at a display, and outputting the synthesized video frame at the display.
